I’m Mathew Nash a 27 year old graduate in Sports Studies and I have an insatiable love for sport. With a particularly keen interest for the madcap world of football I have always been known amongst friends as a beacon for bizarre sporting trivia and knowledge. My other passion is for writing and hopefully combining the two will create a superb and entertaining marriage that will create, divide and share opinion.Mathew is a correspondent for the NextGen Series, Ligue 1 and Primeira Liga.
